In September 2026, astronomers announced that NASA’s Hubble Space Telescope has discovered a massive, 10-sided atmospheric wave—a decagon—encircling Saturn's south pole. This groundbreaking discovery, published in the journal Science Advances, marks the very first time a large, regular-sided geometric jet pattern has been observed in the planet's southern hemisphere. #spacefacts #nasa #cosmos #astronomy #saturn

Japan is proposing a colossal space mission, well space project. They want to build a solar ring around the moon that will be powerful enough to generate energy to the whole planet. The Luna Ring will see a literal ring of solar panels around the moon’s equator 11,000 kms long! #spaceexploration #spacefacts #nasa #cosmos #spacetok

Jupiter does not technically orbit the center of the Sun because it is so massive that their shared center of gravity lies just outside the Sun’s surface. Two objects in space do not simply circle one another’s exact centers; they orbit a shared balance point called a barycenter. #astronomy #spacefacts #cosmos #spacetok #jupiter

If the universe goes on forever and has an infinite number of stars, every line of sight from Earth should eventually hit the surface of a star. This is Olber’s Paradox. #astronomy #spacefacts #cosmos #spacetok #scienceeducation

Where did the big bang happen? Well it actually didn't happen in the traditional sense, like a specific set of coordinates but rather the big bang happened everywhere at the same time. Watch the full video on my YouTube channel. #spacefacts #bigbang #cosmos #astronomy #space

Recent data from a study using the James Webb Space Telescope suggests that a majority of distant galaxies in a specific deep-space survey appear to rotate in the same direction, though this challenges traditional models of the universe. #spacefacts #astronomy #cosmos #nasa #spacetok

This is a map made by NASA’s TESS mission. The Transiting Exoplanet Survey Satellite is a space telescope launched on April 18, 2018, designed to find planets outside our solar system by scanning nearly the entire sky. So far it’s charted nearly 6,000 exoplanets! #spacefacts #astronomy #cosmos #exoplanet

Astronomers have detected the first unambiguous radio signal coming directly from a planet outside our solar system, identified as auroras on the giant exoplanet Beta Pictoris b. The telescope detected rapid, repeating, and highly circularly polarized radio bursts alongside persistent emission (frequencies between 0.85 and 3.5 GHz). #spacefacts #astronomy #cosmos #exoplanet #spaceexploration
